ISL88041

ISL88041 Quad Voltage Monitor The ISL88041 is a quad voltage-monitoring supervisor designed to monitor voltages 0.7V. Low voltage detection circuitry protects the user 's system from low voltage conditions, resetting the system when any of the monitored power supply voltages V1MON-V4MON fall below their respective minimum voltage thresholds. The reset signal remains asserted until all of these voltages return to proper operating levels and stabilize. Each rail’s VMON point is independently adjustable by using an external resistor divider. The VMON inputs will ignore transients of less than 30µs on the monitored supplies, and the RST output is guaranteed to be valid down to VDD = 1V. The RST output is open-drain to allow ORing of multiple signals and interfacing to a wide range of logic levels. Also, the MR input allows the user to assert reset when this input is pulled low.
